Is it possible to rotate a CGImage data without redrawing the image? I would like to impact the orientation of an image in such way that when set as a CALayer content property, the CGImage rotation is taken into account.

Why not simply rotate the layer instead? – DarkDust Mar 13 '14 at 09:45

1@DarkDust it's to use for export in an AVExportSession on an AVSynchronizedLayer , it is said to avoid transforming layers. – Nicolas Manzini Mar 13 '14 at 09:47
